How to Replace Your Water Filter Cartridge: A Step-by-Step Guide


Step 1: Determine When to Replace Your Water Filter Cartridge

The first step in replacing your water filter cartridge is to determine when it's time for a change. Most manufacturers recommend changing the cartridge every six months or after filtering a specific volume of water. It's essential to consult your filter's documentation or check the manufacturer's website for specific guidelines.

Step 2: Purchase a Replacement Water Filter Cartridge

Once you know it's time for a change, you'll need to purchase a new water filter cartridge. You can find replacement water filter cartridges at various locations, including online retailers such as Awesome Water Filters. They offer a wide range of cartridges, including their 8-stage and 7-stage options.

For those based in Australia, you can find water filter cartridges in Sydney, Melbourne, and other major cities through their website.

Step 3: Turn Off the Water Supply

Before you begin the water filter cartridge replacement process, ensure that you turn off the water supply to your kitchen water filter tap. This will prevent water from flowing while you're working on the filter and help avoid any potential mess.

Step 4: Remove the Old Water Filter Cartridge

Depending on the type of cartridge water filter system you have, you may need to remove a housing or cover to access the old cartridge. Follow the manufacturer's instructions to open the filter housing. Once you have access to the cartridge, twist or pull it out of the housing, depending on the design. It's a good idea to have a bucket or towel nearby to catch any water that may spill during this process.


Step 5: Clean the Filter Housing

Before installing the new water filter replacement cartridge, clean the filter housing. Use a soft cloth or sponge and mild soap to clean the interior, removing any sediment or debris. Rinse the housing thoroughly with clean water to remove any soap residue.

Step 6: Install the New Water Filter Cartridge

Now that the filter housing is clean, it's time to install the new cartridge. Carefully unwrap the new water filter cartridge and follow the manufacturer's instructions for installation. Usually, this involves inserting the cartridge into the housing and twisting or snapping it into place.

Step 7: Reassemble the Filter Housing

With the new cartridge installed, reassemble the filter housing or cover. Ensure that all seals and connections are secure to prevent leaks during operation.


Step 8: Turn the Water Supply Back On

Once the new water filter cartridge is in place and the housing is reassembled, turn the water supply back on. Check for any leaks around the filter housing, and tighten any connections if necessary.

Step 9: Flush the New Cartridge

Before using the water from your filter taps, it's essential to flush the new cartridge. This will remove any air bubbles and ensure that the water is properly filtered. To do this, run the water through the filter for a few minutes, or follow the manufacturer's recommendations for flushing. You may notice that the water appears cloudy initially; this is normal and should clear up as the cartridge is flushed.

Step 10: Reset the Filter Replacement Indicator (If Applicable)

Some water filter systems have a built-in filter replacement indicator to remind you when it's time for a new cartridge. If your system has this feature, reset the indicator according to the manufacturer's instructions.

Step 11: Dispose of the Old Water Filter Cartridge Responsibly

After completing the water filter cartridge replacement, it's essential to dispose of the old cartridge responsibly. Many cartridges can be recycled, so check with your local recycling facility or the cartridge manufacturer for recycling options. If recycling is not available, dispose of the cartridge in your regular household waste.



Replacing your water filter cartridge is a simple and essential maintenance task that ensures you always have clean, healthy water on tap. By following this step-by-step guide, you can confidently replace your cartridge and maintain the performance of your water filter system.
